True/False
Indicate whether the statement is true or false.
 

 16. 

ERP (enterprise resource planning) defines a general architecture, omitting standards for data, processing, network, and user interface design.
 

 17. 

A Web-based application encounters all of the connectivity and compatibility problems that typically arise when different hardware environments are involved.
 

 18. 

A high-capacity transaction processing system, such as an order entry system, requires less network, processing, and data storage resources than a monthly billing system that handles data in batches.
 

 19. 

In a typical client/server system, the client stores the data and provides data access and database management functions.
 

 20. 

Implementation of early client/server systems was expensive because clients needed more powerful hardware and software to handle shared processing tasks.
 

 21. 

Today, client/server architecture is the dominant form of systems design, using Internet protocols and traditional network models.
 

 22. 

Middleware provides a transparent interface that enables system designers to integrate dissimilar software and hardware.
 

 23. 

As the size of a business changes, it is easier to alter the capability of a large-scale central server than it is to adjust the number of clients and the processing functions they perform.
 

 24. 

In contrast to a centralized system, a client/server design separates applications and data.
 

 25. 

In a Web-based system, portal design provides an important link between the user and the system, and poor design can weaken system effectiveness and value.
 

 26. 

A user’s computer does not perform processing or computing tasks with cloud computing — the cloud does.
 

 27. 

Web 2.0 is a reference to a more technically advanced version of the current Web.
 

 28. 

TCP/IP consists of many individual protocols that control the handling of files, mail, and Internet addresses, among others.
 

 29. 

One disadvantage of a hierarchical network is that if a business adds additional processing levels, the network becomes more complex and expensive to operate and maintain.
 

 30. 

Various types of individual and site licenses are available from software vendors.
 

Completion

 31. 

____________________ translates the logical design of an information system into a physical structure that includes hardware, software, network support, and processing methods.
 

 

 32. 

Many companies are extending ERP systems to suppliers and customers in a process called ____________________, in which a customer order can cause a production planning system to schedule a work order, which in turn triggers a call for certain parts from suppliers.
 

 

 33.

 34. 

If a system must operate online, 24 hours a day and seven days a week (typically known as ____________________), provision must be made for backup and speedy recovery in the event of system failure.
 

 

 35. 

Company-wide systems that connect one or more LANs or WANs are called ____________________.
